[opensuse-kernel] kernel-docs package
by Jeff Mahoney 11 Dec '09

11 Dec '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 In going through the openSUSE kernel bug queue, I ran across one against kernel-docs. The spec file for that package is... entertaining. It starts off by doing a cp -a /usr/src/linux* into the build dir. That might've been a good idea at one point, but it's hardly one anymore. I propose that we make kernel-docs a linked package to the kernel-source package and BuildRequires the kernel-source package. The documentation can be generated with a make -C $SRC O=$PWD instead, negating the need to copy _anything_. Making it a linked package means that the version numbers get set automatically by mkspec. Right now, the kernel-docs package is version 2.6.3 but built against whatever kernel-source is in the repo. - -Jeff diff --git a/rpm/kernel-docs.spec.in b/rpm/kernel-docs.spec.in new file mode 100644 index 0000000..d7ff3b1 - --- /dev/null +++ b/rpm/kernel-docs.spec.in @@ -0,0 +1,97 @@ +# +# spec file for package kernel-docs@VARIANT@ (Version @RPMVERSION@) +# +# Copyright (c) 2009 SUSE LINUX Products GmbH, Nuernberg, Germany. +# +# All modifications and additions to the file contributed by third parties +# remain the property of their copyright owners, unless otherwise agreed +# upon.

[opensuse-kernel] Fate #306591: entropy daemons in 11.2 - Kernel Removal IRQF_SAMPLE_RANDOM
by Rob OpenSuSE 10 Dec '09

10 Dec '09

I have taken an interest in Fate #306591 https://features.opensuse.org/306591 Andreas Jaeger has mused on community volunteer to package something. Now, I took a look at few suggestions, but 2 of them weren't "just work" in sense that they required webcam or mic, which seems like a possible can of worms to me. So I wondered about using timing jitter from user space? As a prototype I've knocked up short piece of C, which uses calls : nanosleep( &tsleep, 0); clock_gettime(CLOCK_REALTIME, &ttnow) This has been tested on i686 Athlon MP & P4 (Celeron Willamette) and x86_64 Athlon 64 x2; and I do appear to get a useful amount of unpredictable bits from this, even if the raw timings are not random. The timing jitter provides an externally unobservable measurement, and would allow sysadmin to tune to some extent eg) run 10 times/s (80bits/s) - 25 times/s (400bits/s). If this sounds like a useful approach, then I'd propose to continue on and develop a small daemon which gathers entropy bits from timing unpredictabilities caused by scheduler & interrupts, and also periodically gathers extra entropy (especially on startup) borrowing from techniques uses in the perl egd daemon (which would need modifying in any case). Obviously I'm a bit concerned about any move on power saving, this would obviously requires N wake ups, perhaps precautions would be needed to avoid them getting squeezed together by power saving patches which aim to batch up, code that sleeps like this?

[opensuse-kernel] keeping the 10.3 kotd?
by Michal Marek 09 Dec '09

09 Dec '09

Hi, openSUSE 10.3 is EOL and so is the SL103_BRANCH in kernel git. I see there is one more patch that was committed after the last kernel update: commit 874207faf01e7231972a2ba30b9c7a6e7722f48a Author: Suresh Jayaraman <sjayaraman(a)suse.de> Date: Tue Aug 25 19:40:20 2009 +0530 - patches.fixes/cifs-fix-overflow-in-cifs_readdir: cifs: Increase size of tmp_buf in cifs_readdir to avoid potential overflows (bnc#492282,CVE-2009-1633). Is there interest in keeping the 10.3 kotd for a while? Deleting it would save some 3GB on ftp.suse.com, so unless someone really wants the packages, I'll nuke them: du -m SL103_BRANCH/ | sort -n 53 SL103_BRANCH/src 658 SL103_BRANCH/ppc 857 SL103_BRANCH/x86_64 1479 SL103_BRANCH/i586 3046 SL103_BRANCH/ Alternatively, I can delete the debuginfos and keep the runtime packages for some time: du -m --exclude='*-debuginfo*' SL103_BRANCH/ | sort -n 53 SL103_BRANCH/src 98 SL103_BRANCH/ppc 125 SL103_BRANCH/x86_64 170 SL103_BRANCH/i586 445 SL103_BRANCH/ Of course, if someone wants to provide fixes for the SL103_BRANCH, I'll happily merge and build them, but I don't think that many people are interested in the 2.6.22 kernel ;).

[opensuse-kernel] tracer in 2.6.32...
by Matthias Hopf 08 Dec '09

08 Dec '09

Hey all, any particular reason why approximately all tracers in the kernel are not compiled as modules by default in 2.6.32rc? In particular, I'm interested in the sysprof tracer, because I use sysprof every now and then. I checked the config, and all CONFIG_*_TRACER are not set. I don't see the reasoning behind that ATM, as the according tracer can only be loaded and activated by root.

[opensuse-kernel] "Warning! ehci_hcd should always be loaded before ..." message still there in kernel 2.6.27.37-0.1
by Fred Scali-West 05 Dec '09

05 Dec '09

Hi, I assume that this is the right list to post it (rather than opensuse-bugs), but I may be wrong, so any comments are welcome... The issue triggering the message (in dmesg) "Warning! ehci_hcd should always be loaded before uhci_hcd and ohci_hcd, not after" is stil there in last kernel update (uname -a = Linux mir 2.6.27.37-0.1- default #1 SMP 2009-10-15 14:56:58 +0200 i686 athlon i386 GNU/Linux). As discussed between list users Jean Delvare & Greg KH in message- id:<200905051826.54284.jdelvare@xxxxxxx> from 5 May 2009, the 2 ending lines here (in /etc/modprobe.conf): # "Warning! ehci_hcd should always be loaded before uhci_hcd and ohci_hcd, not # after" (bnc#449853) # mkinitrd hints: # SUSE INITRD: uhci-hcd REQUIRES ehci-hcd # SUSE INITRD: ohci-hcd REQUIRES ehci-hcd install uhci-hcd /sbin/modprobe ehci-hcd; /sbin/modprobe --ignore-install uhci-hcd install ohci-hcd /sbin/modprobe ehci-hcd; /sbin/modprobe --ignore-install ohci-hcd are missing in the /etc/modprobe.conf from /boot/initrd-2.6.27.37-0.1-default. Manually modifing the file in the initrd (and appending the 2 missing lines) solved again the issue, so that would be really nice to get rid definitively of this problem as soon as possible...

[opensuse-kernel] KOTD/HREAD: kernel source not in sync again
by Markus Koßmann 04 Dec '09

04 Dec '09

Since Wednesday, there were three updates of KOTD/HEAD and with none of them the provided kernel source version was in sync with the provided binaries. Another observation:When there were a few days without update, in many cases the next update is out of sync and only the following update is in sync again -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-kernel+help(a)opensuse.org
